Abstract

After the intense Alaskan earthquake of 27 March 1964, unusual waves up to 6 feet (about 2 meters) in height occurred at about the time of arrival of seismic waves at many localities along the coasts of Louisiana and Texas. The parameters of local channels at the tide gauge in Freeport, Texas (the only instrument to record significant waves) yield seiche periods close to those of the seismic surface waves suggesting that the water waves were generated by and in resonance with the seismic waves.
